This is a worthy thesis. I don't know if I entirely agree. Flat stomach+thin waist+big tits could equal or Trump your combo. Perhaps we should refine it to state that flat stomach and thin waist are mandatory, in combination with some show of femeninity elsewhere (could be wide hips, could be big tits).

you guys have well, different taste. the ideal waist to hip ratio is well documented to be difference by race of the observer:

Other studies have identified body shape, or waist-to-hip ratio, as an important feature of female attractiveness for which Caucasian and African-American men may have different preferences. Low WHR, typically defined as .68–.80, has been suggested to be an indicator of reproductive health and fertility (Henss, 1995; Singh, 1993, 1994a,b,c) and also a signal of the absence of major diseases (Bjorntorp, 1988, 1991; Leibel, Edens, & Fried, 1989). Thompson et al. (1996) found African-American males were 1.9 times more likely to select a larger ideal female hip/buttocks size and 1.7 times more likely to choose a larger ideal female thigh size than Caucasian subjects. Evidence from other investigations demonstrated that African-Americans indicated a greater attraction to heavier figures than did Caucasian men, including a higher ideal weight and a preference for larger buttocks (Cunningham, Roberts, Barbee, Druen, & Wu, 1995). Similarly, in a recent study, Freedman, Carter, Sbrocco, and Gray (2004) found that African-American men often preferred WHRs in the range of .55–.65. They found that in addition to being more accepting of larger body sizes for women, African-American men preferred a WHR that was lower than the WHR preferred by Caucasian men. Such findings lend support to the notion that men’s weight and shape preferences constitute cultural variants that may contribute to the maintenance of unhealthy weights among African-American women. However, not all studies have supported these conclusions. Although Singh (1994a,b,c) found that African-American men did not prefer heavier women, the range of WHRs presented to participants was restricted (.70 through 1.0). Additionally, participants were only presented with figures that were Caucasian in appearance.
